Thahn Nguyen's family has owned the DC Gas Station for about 15 years. In all of those years welcoming customers, they've also had a share unwelcome visitors.
"About ten years ago my mom did get robbed once and ever since then we exercise our right to open carry," Nguyen said.
Nguyen says the shooting at another convenience store shows how some gas station attendants are willing to fight back.
"it sends a message that we are willing to protect ourselves when push comes to shove, but it's unfortunate that a man had to die for store owners to be able to stand up for that right." Nguyen said.
While most stores have signs prohibiting concealed carry, the DC Gas Station actually welcomes it.
"My brother and I all carry. Normally we open carry," Nguyen said. "Somebody comes in on a bad day and they want to come in and take anything they want, we are always going to defend it. I don't want to hurt anybody or take anybody's lives, when push comes to shove I will defend my safety.
The robbery reminded Nguyen of the dangers of his job and the need to be prepared.
"If it happens down the street it can happen down here anytime," Nguyen said.
